    摘要： Motor drives and control methods are presented for sensorless motor speed control in which inverter output currents are sampled from the inverter output and a frequency modulation value is determined based on the current feedback. A speed or frequency setpoint is adjusted at least partially according to the frequency modulation value to provide an adjusted frequency or speed setpoint value that is then used in controlling the inverter to provide stability control to mitigate hunting or motor stoppage.

    摘要： An active and passive boundary layer control system and method for reducing boundary layer separation and the resulting form drag from ground vehicles. Tubings with multiple venturis connected in series are attached to the side and/or roof of the ground vehicle. A flow of compressed air is created by an engine auxiliary, e.g., a turbocharger or a supercharger, or by a designated blower and injected into the tubings. Suction created by the venturis actively removes decelerated fluid from the boundary layer and keeps the boundary layer flow attached. Optionally, the system exhausts the air in concentrated free jets along the vehicle body to a series of passive boundary layer control devices, such as vortex generators.

    摘要： The present disclosure describes combination discus locks and associated methods. A lock device configured in accordance with a particular embodiment of the present disclosure includes a discus lock housing, a locking mechanism positioned in the lock housing, and a plurality of rotatable wheels operably coupled to the locking mechanism. The rotatable wheels can individually have a plurality of indicia used to display a combination. The locking mechanism can be configured to move from a locked configuration to an unlocked configuration when the combination is displayed. The lock device can further include a shackle and a slider actuator positioned on an outer surface of the lock housing. The slider actuator can be operably coupled to the shackle and to the locking mechanism, and can be configured to drive the shackle from a closed position to an open position when the locking mechanism is in the unlocked configuration.

    摘要： A laser projection system includes at least one laser light source, a projection screen and a spatial light modulator for projecting a laser beam of the laser light source to form an image on the projection screen. The projection screen includes a luminescent layer which upon excitation by the laser beam emits blue light. The luminescent layer contains MSi6−aAlaN8−aOx+a:Eu2+ (with M=Sr, Ba,; 0≦x≦1; 0≦a≦1) as a luminescent material. With this material laser light of a laser diode emitting in the wavelength region of 405 nm can be converted to blue light of 450 nm with high efficiency. The proposed projection system, therefore, is suitable for RGB projection using laser diodes as laser light sources.
